initfs: Add flash clear and update during init

Add code to clear the rwfs (preserving files from the whitelist)
during init, by a command line option.

Also allow it to be triggered by the file system not being a jffs2.

A console user can download images to /run/initramfs/ at the
debug-init-sh prompt for manual update.

Also add code but do not enable detecting images loaded into
initramfs / for future update options.  If enabled a custom initrd
with update images can be bulit (it would not fit in flash and
need to be netbooted).

Build Status

Building

OpenBMC uses Yocto/Open-Embedded for a build system, which supports an out-of-tree build. It is recommended that you create an empty directory somewhere to hold the build. This directory will get big.

On Ubuntu 14.04 the following packages are required to build the default target

sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat

On Fedora 23 the following packages are required to build the default target:

sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake
sudo dnf groupinstall "C Development Tools and Libraries"

To start a build:

cd <builddir>
. <repodir>/openbmc-env
bitbake obmc-phosphor-image
